Math - [Lesson 3.3]

Teacher: Mr. Kovalik (408) 314-1092

Objective and Summary:
SWBAT use rectangular array models to represent the distributive property
1

Draw--Use a rectangular array model to write an equivalent expression.

4(2y+9)

CFS:
#1: Accurately represents expression with area model
#2: Accurately multiplies all terms

1

Distribute--Use the distributive property to write an equivalent expression in standard form.

3(2x+5)

CFS:
#1: Accurately multiplies all terms

1

Distribute--Use the distributive property to write an equivalent expression in standard form. Optional SYW in Formative

-4(-3y+8)

CFS:
#1: Accurately multiplies all terms

MEDIUM PROBLEMS
1

Skill and Drill--Use the distributive property (draw arrows and multiply) to write equivalent expressions in standard form. Optional SYW in formative.

-9(9a+5)

CFS:
#1: Accurately multiplies all terms

1

Check ALL--Which expressions are equivalent to -8(7x-2)?

Select ALL that apply.

1

Now with Three Terms--Use the distributive property (draw arrows and multiply) to write equivalent expressions in standard form.

12(10-4x-3y)

CFS:
#1: Accurately multiplies all terms

4

Use the distributive property to rewrite the expression 9(5x-2) in standard form.

**You MUST SYW in formative for credit**

CFS:
#1: Accurately multiplies all terms
